'The fascism of Nazi Germany belongs to a world so horrendous it often seems to defy the possibility of repetition or analogy. But Dr. Stern, 78, the author of books like "The Politics of Cultural Despair: A Study in the Rise of the Germanic Ideology" and university professor emeritus at Columbia University, has devoted a lifetime to analyzing how the Nazi barbarity became possible. He stops short of calling the Christian right fascist but his decision to draw parallels, especially in the uses of propaganda, was controversial.

'"When I saw the speech my eyes lit up," said John R. MacArthur, whose book "Second Front" examines wartime propaganda. "The comparison between the propagandistic manipulation and uses of Christianity, then and now, is hidden in plain sight. No one will talk about it. No one wants to look at it."'
